Oracle Error Message
ORA-16635: network connection failed during transmission
Reason for the Error
The Data Guard broker detected a connection failure to a remote database in the broker configuration. This failure happened in the middle of a transmission session. A transmission session usually requires more than one send operation for sending a large amount of data (for example, the broker configuration file) to the remote database.
Solution
In most cases, no user action is required. The Data Guard broker always tries to resend the data. This error will be reported if the problem persists. This error indicates there are some problems with the network connection between broker managed databases. Further network troubleshooting should be done to identify and correct the actual problem.
